Super quiet box type low-noise and high-efficiency heat dissipation customized diesel generator set

🔇 1. Excellent low noise performance
Multi-layer sound insulation design: adopting the three-layer composite structure of ‘cold-rolled steel plate + sound-absorbing cotton (50mm) + aluminium foil reflective layer’, combined with the impedance mismatch anechoic system, the noise can be controlled at 65-75dB(A) at 7m, and some new models can even be lowered to 68dB(A) (at 1m), which is about 1/3 lower than that of ordinary units. The noise level can be reduced to 68dB(A) (at 1 metre), which is about 1/3 lower than that of ordinary units.

Optimisation of air ducts: The reflux air duct design effectively suppresses high-frequency whistling while improving the cooling efficiency by 20%.

⚙️ 2. High-efficiency power system and environmental performance
Core engine: equipped with Weichai's self-developed WP10/WP13 series diesel engine (e.g. WP10D320E200), adopting high-pressure common rail technology (rail pressure up to 1,800bar), precise control of fuel injection, mechanical noise ≤ 85dB, fuel consumption rate as low as 197-226g/kW-h179.

Environmental protection emission: meets the National III off-road emission standard (NOx≤3.5g/kWh), and some models are compatible with EU Stage V, adapting to low-carbon application scenarios.

Vibration-damping technology: Hydraulic suspension shock absorber + rubber base double damping, structural sound transmission is reduced by 40% to ensure smooth operation.

⚡ 3. Stable Electrical Performance
Voltage/frequency control: steady state voltage adjustment rate ≤ ± 0.5%, transient adjustment rate ≤ ± 15%; frequency fluctuation rate ≤ 0.5%, recovery time ≤ 3 seconds, support 0.8 power factor output, suitable for power supply of precision equipment.

Generator configuration: matching brushless self-excited generator (such as Marathon, Leroy Somer brand), H-class insulation, IP22 protection level, voltage waveform distortion ≤ 5%, to ensure the purity of power output.

🏗️ 4. Compact structure and strong environmental adaptability
Integrated design: compact structure of silent box (typical size about 3040×1240×1815mm), weight about 2.7-2.8 tonnes, the base tank supports full load operation for 8-10 hours, reducing frequent refuelling.

All-weather operation: passed the ‘three highs’ (high altitude, high temperature, high cold) test, standard air intake heater, support -25℃ cold start, 3000m altitude power does not decay.

Enhanced protection: galvanised sheet + double-layer spraying on the box, anti-rust and anti-condensation, adapting to harsh environments such as salt spray, sand and dust.

📱 5. Intelligent control and security
Intelligent monitoring system: optional full-automatic ECU control, supporting remote telemetry, remote control, fault diagnosis (such as overspeed, high water temperature, low oil pressure and other fourfold protection), some models support unattended operation.

Convenience of operation: mute box with observation window, emergency stop button, maintenance door quick-open design, cartridge replacement cycle up to 500 hours, reducing maintenance costs.

🌍 6. Complete certification and global service
International Certification: Comply with ISO 8528, GB/T2820 standards, passed ISO9001 quality management system and CE/TLC certification.

Service Guarantee: Provide 12 months or 1000 hours warranty, global 5600+ service network coverage, fault response time ≤ 24 hours (12 hours in place domestically).

💎 Summary
With the core advantages of low noise (≤75dB), high stability (voltage/frequency fluctuation rate <1%), strong environmental adaptability (-25℃~50℃/3000m altitude) and intelligent control, the Weichai 300KW mute unit is especially suitable for noise-sensitive scenarios such as hospitals, data centres, and high-rise buildings with emergency power supply.146 Its modular design, long-cycle maintenance, and global joint warranty further enhance the Its modular design, long-cycle maintenance and global warranty further enhance the economy and reliability of use, and is a mature solution for industrial-grade silent power supply.
